Results of the verification activities

This deliverable presents the corpus of verification activities performed in Task 5.1 for the three open-source advanced computational tools addressing the thermomechanical behaviour of nuclear fuel elements considered in the OperaHPC project, i.e.: the MMM mesoscale code, the multiscale meshless SPH method based prototype tool, and the OFFBEAT engineering fuel rod scale code, coupled with the SCIANTIX code. Intended as the first component of the key VVUQ&SA process towards their qualification for nuclear safety studies, these verification activities encompass comparison of computational results with analytical and/or manufactured solutions in simple configurations, as well as code-to-code comparison with existing advanced multidimensional fuel performance codes (ALCYONE, BISON, Falcon) developed and/or used by OperaHPC partners on specific case studies consistent with the applications targeted in WP7 for which those codes are validated against experimental data. Acceptance criteria are detailed and shown as met in general terms.
